Product details
Overview
PMEG2020EPK from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for ultra-low forward voltage operation in space-constrained DC/DC converters and mobile LED backlighting. It delivers VF ≤ 450 mV at IF = 2 A, VR = 20 V, and reverse recovery time trr ≤ 5 ns, housed in a leadless DFN1608D-2 (SOD1608) package with solderable side pads.
For engineers reviewing the PMEG2020EPK datasheet, PMEG2020EPK pinout, PMEG2020EPK application, or PMEG2020EPK equivalent, this device is selected for high-efficiency low-voltage rectification where thermal performance, ultra-small footprint, and fast switching are critical - especially in battery-powered portable electronics and compact power modules.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its ultra-low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency at low voltages without sacrificing reverse leakage control.
The DFN1608D-2 package features side-wettable flanks (SWF) for automated optical inspection (AOI) of solder joints and achieves Rth(j-sp) = 20 K/W to cathode solder point on ceramic PCBs - critical for thermal management in high-density layouts where board area and height (<0.37 mm typ.) are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - supports input rails up to 18 V DC with margin for transients in USB-powered or Li-ion-based systems. |
| Forward Voltage (VF) | 395 mV (typ.) at 2 A - reduces conduction loss by >30% vs. standard Schottkys, directly improving efficiency in 3.3 V/5 V buck converter outputs. |
| Reverse Recovery Time (trr) | 5 ns (max) - enables stable operation at >10 MHz switching frequencies without tail current losses or EMI spikes. |
| Average Forward Current (IF(AV)) | 2 A (at Tamb ≤ 65 °C on FR4) - sustains continuous load in compact 1 A-rated power stages with derating headroom. |
| Reverse Current (IR) | 350 µA (max) at VR = 10 V - ensures minimal standby power drain in always-on circuits like real-time clocks or sensor bias rails. |
| Diode Capacitance (Cd) | 50 pF (max) at VR = 10 V - limits capacitive loading on high-speed gate drivers or RF-coupled signal paths. |
| Thermal Resistance (Rth(j-sp)) | 20 K/W - allows direct thermal coupling to PCB copper, enabling >1.5 W dissipation with <30 °C junction rise above solder point. |
Pinout & Package
Encapsulated in a leadless ultra-small DFN1608D-2 (SOD1608) plastic package measuring 1.6 mm × 0.8 mm × 0.37 mm, with visible and solderable side pads for AOI-compatible reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; marked with cathode bar; connects to output rail or ground return path; primary thermal path to PCB via exposed pad. |
| 2 (A) | Anode | Current entry terminal; connects to switch node or input rail; side-wettable flank enables reliable solder joint inspection. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents edge breakdown under voltage transients, increasing surge robustness without external TVS in low-energy DC/DC stages. |
| Solderable side pads | Enables automated optical inspection (AOI) of solder fillets - essential for zero-defect manufacturing in consumer wearables and medical patches. |
| Ultra-low profile (0.37 mm) | Permits placement under connectors or beneath thin-film shields in <1 mm total stack-up designs such as foldable phone displays. |
| Low reverse current (70 µA typ.) | Maintains battery shelf life >10 years in coin-cell–powered IoT sensors by minimizing leakage across backup rails. |
| Side-wettable flank (SWF) | Ensures IPC-A-610 Class 3 compliant solder joints without X-ray inspection - reducing test cost in high-volume mobile production. |
Applications
| Mobile LED Backlighting | USB-C Power Delivery Output Rectification |
|---|---|
|

IC Role / Device Role / Timing Role: Series-connected polarity guard with minimal forward loss in always-on backup paths. Use Value: 230 mV VF at 100 mA ensures >97% voltage retention across protection diode - avoiding brownout resets in timekeeping circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TR | Higher VF (490 mV @ 1 A), larger SOD-123FL package (3.5 mm × 1.6 mm), no side-wettable flanks. | Less suitable for AOI-driven high-volume mobile assembly; requires larger PCB area and higher thermal resistance. | Select only when legacy footprint compatibility outweighs efficiency and miniaturization goals. |
| SS12HE3_A/H | Lower VR (20 V same), but VF = 500 mV @ 1 A, TO-277 package (4.5 mm × 2.7 mm), no guard ring. | Not viable for sub-1 mm height designs; lacks transient edge protection needed in noisy automotive accessory rails. | Consider only for industrial non-miniaturized supplies where cost is prioritized over thermal density and reliability margin. |
Compared with RB050M-40TR and SS12HE3_A/H, PMEG2020EPK provides superior power density (0.37 mm height), lower conduction loss (−105 mV at 1 A), and built-in stress protection - making it the optimal choice for next-gen portable electronics where board space, efficiency, and manufacturability are co-constrained.

FAQ
What is the maximum junction temperature rating for PMEG2020EPK?
The absolute maximum junction temperature (Tj) is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating curves in Figures 10–13 show usable IF(AV) versus ambient or solder-point temperature, with full 2 A rating maintained only below 65 °C ambient on standard FR4.
Does PMEG2020EPK support reflow soldering with standard lead-free profiles?
Yes - the DFN1608D-2 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. Figure 18 provides exact solder land dimensions and paste deposit guidelines; side-wettable flanks ensure process robustness across conveyorized reflow lines used in smartphone and wearables manufacturing.
Is PMEG2020EPK automotive-qualified?
No - per Revision History (Section 14), this part was explicitly changed to non-automotive qualification in v.3 (2025). It lacks AEC-Q101 stress testing and is not approved for use in safety-critical or engine-compartment applications. Automotive alternatives are designated with "-Q" suffixes and listed separately on nexperia.com.
How does the guard ring affect layout requirements?
The integrated guard ring eliminates need for external field plates or increased clearance around the die. Layout follows standard SOD1608 footprint (Figure 18); no extra keep-out zones or guard traces are required. This simplifies routing in dense power IC layouts while maintaining >2 kV HBM ESD robustness without added capacitance.
